JOINTER ATTACHMENT FOR PLG'WS.

Specification of Letters Patent.

Patented Aug. 11, 1914.

Application filed November 21, 1912. Serial No. 732,741.

To all whom it may concern:

Be it known that I, PHILIPS. SIDELL, a citizen of the United States,residing at Shreve, in the county of Wayne and State of Ohio, haveinvented a new and useful Jointer Attachment for Plows, of which thefollowing is a specification.

This invention relates to jointer attachments for plows and is moreparticularly designed as an improvement upon the structure shown inPatent No. 946,279, issued to me on January 11, 1910. In structures ofthis type as heretofore devised, considerable difiiculty has beenexperienced by reason of the fact that trash has accumulated between theplow and the point of the jointer blade thus renderin the deviceinefficient for the purposes intended. This trouble has been due to thefact that the jointer blade has been spaced a sufficient distance fromthe plow to admit foreign substances which have become hung thereon.Furthermore, jointer blades as heretofore utilized have been arranged infront of the plow. Consequently, should there be an unyieldingobstruction in front of the plow, said obstruction would be hit by thejointer blade. Thus the blade would be injured.

One of the objects of the present invention is to provide a jointerblade which is arranged to contact with one side f the plow, cotterdisk, or other soil engaging element at a point back of the frontextremity of said element, this jointer blade being so arranged as toengage and cut off the sod on the furrow slice and turning it into thefurrow.

Another object is to provide a jointer blade which, by contacting withthe side of the soil engaging element, prevents trash from accumulatingbetween said element and jointer blade. 7

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, can be made within thescope of what is claimed, without departing from the spirit of theinvention.

In the accompanying drawings the preferred form of the invention hasbeen shown.

"of Fig. 1.

In said drawings :-Figure l is a perspective view of a plow having thepresent improvements combined therewith the parts being arranged to turnthe soil to the left of the plow. Fig. 2 is a section on line AB Fig. 1.Fig. 3 is a transverse section through the jointer blade and showing themeans for connecting it adjustably to its stem, said section being onthe line C-D Fig. i is a side elevation showing a modified arrangementof the jointer blade, the same being combined with a disk colter, theparts being arranged to turn the soil to the right of the plow. Fig. 5is an end elevation of certain of the parts shown in Fig. 1.

Referring to the figures by characters of reference 1 designates a soilengaging element in the form of an ordinary furrow opening plow having astandard 2. EX- tending forwardly along one side of the standard 2 andin a substantially horizontal plane, is the arm 3 of the jointerattachment, this arm being held on the standard 2 by U-bolts a the endsof which are mounted within a clamping plate 5 mounted on one side ofthe standard. The front end of the arm 3 is broadened to form a head 6,this head being provided with oppositely extending slotted portions 7designed to receive bolts 8. These bolts extend backwardly from theblade 9 of the jointer, this blade being preferably in the form of aminiature plow and having one side edge contacting with one side of theplow 1 up to the point 10 of the jointer blade. By mounting the bolts 8in slots i", it will be apparent that the jointer blade can be adjustedlaterally so as to bring its inner side edge into contact with the sideof the plow 1. With the device thus arranged it will be seen that whenthe plow is drawn forward, the sod will be cut off of the furrow sliceby the ]OlIl13I' blade and turned down into the furrow. As the jointerblade contacts with the side of the plow, there is no danger of trashaccumulating between the two parts and interfering with the properoperation of the at tachment. Furthermore it will be seen that the pointof the plow extends forwardly beyond the point 10 of the jointer bladeand, therefore, there is no danger of the jointer blade coming intocontact with any obstructions which may be in the path of the plow.Instead the plow itself will strike the obstruction and the j ointerblade will thus be shielded from injury.

WVhile the jointer attachment is preferably designed for use inconnection with a furrow opening plow such as shown in Figs. 1 and 2, itis to be understood that it can be used in connection With other formsof soil engaging devices. For example, and as shown in Fig. 4, thejointer blade 11 can be extended into contact with one side of a oolte rdisk 12 supported from the ploW beam 13, the .jointer blade in thisinstance, operating in the same manner as hereinbefore described andhaving the additional function of a scraper for removing accumulationsfrom the disk.

Copies of this patent may be obtained for edge with one side of the soilengaging de' vice.

In testimony that I claim the foregoing as my oWn, I have hereto aflixedmy signature in the presence of tWo Witnesses.
